I have annoying problem with ftp. I have: ASA 5510 with active IPS. In DMZ I have several servers. Every day I have to puts many files via ftp from workstations in LAN connected to ASA inside interface. Connection work fine, but for each one file ftp client waits ~60 secounds after transmission. When I have turned off the IPS everythings work fine. I did several test with IPS rules and any give correct results. Example: I turned off every rules for FTP.
Could you tell me what is wrong with ASA or IPS configuration?
Best regards Arek
